Design Context Skill

Ensures wireframes and UI decisions leverage existing patterns from the design system, Storybook, and codebase.

When to Use

• Before presenting wireframes (Ask mode DIVERGE)
• Before implementing UI changes (Agent mode)
• At every DIVERGE Loop to stay grounded in existing patterns

Instructions

Phase 1: Design System Check

Read the design system documentation:

Read /docs/design-system/components.md
Read /docs/design-system/spacing.md
Read /docs/design-system/colors.md (if color decisions needed)
Read /docs/design-system/interactions.md (if interaction patterns needed)

Note applicable: - Design tokens (h-13, px-4, gap-3) - Component patterns (Button variants, DataTable, Dialog) - Spacing conventions (p-4 for cards, gap-6 for sections)

Phase 2: Storybook Patterns

Find existing component stories:

Glob **/*.stories.tsx

Identify: - Components matching current wireframe needs - Existing variants and props - Documented states (loading, error, empty)

Key story locations: - /src/stories/ - General component stories - /features/*/components/*.stories.tsx - Feature-specific stories

Phase 3: Codebase Search

Search for similar UI patterns:

SemanticSearch "How is [pattern] implemented in the codebase?"

Look for: - Similar features already built - Reusable hooks and utilities - Existing layout patterns

Phase 4: Library Documentation (Context7 MCP)

Query library docs for unfamiliar patterns:

1. resolve-library-id with libraryName (e.g., "radix-ui")
2. query-docs with libraryId and specific question

Common libraries: - /radix-ui/primitives - Dialog, Dropdown, Select patterns - /tanstack/query - Data fetching patterns - /tanstack/table - Table patterns

Output Format

After running this skill, output:

## Design Context

| Source | Relevant Patterns |
|--------|-------------------|
| Design System | [tokens, components] |
| Storybook | [stories that apply] |
| Codebase | [existing implementations] |
| Libraries | [patterns from docs] |

### Applicable Components
- [Component]: [How it applies to current wireframe]

### Design Tokens to Use
- Spacing: [tokens]
- Colors: [tokens]
- Typography: [tokens]
